I too was shocked the first time I heard them "munching" on Echo's hull
. Our only other sailboat we had was Phoenix, our Cal
9.2 up in Lake Texoma, and were used to the sounds of Carp munching on alge on our hull. We had cleaned all the barnacles
off Echo's hull, and I still here the "snap, crackle and pop" going on, night and day. I thought, OMG! Blisters!!!! Oh well, we live and learn don't we...... LOL!
